The thing about race car wings ... F1, Supecar, Touring car ... is that they need to work at a range of speeds. There has been some cool #cheating in F1 where the mount for the rear wing was made weak so that it flexed (altering the angle of attack) and created less downforce/drag at high speed (they weren't supposed to have adjustable aero). But it shows that the static design was weighted towards low speed downforce.

My wing also needs to work across a range, but it's from 180mph, where I think I'm starting to loose traction and 220mph, where I recon I will definitely be challenged.

I like glider wing design as a precedent because they don't have a motor, so simultaneously can't tolerate drag and need something to lift them up. They seem to be thin and long.

Hi Russ, the D2954 is what I've been using for years with no issues. It fits to a 15" rim which opens your options and the OD is same as hayabusa which means your ratios will be OK. These tyres do grow by up to 2" at speed even when pumped to 100 psi.
The guys at North Terrace Tyres are good to deal with
